Experimental study of performance and modification of polyester-type and polyether type superplasticizer

Based on the different performance of polyester-type and polyether-type superplasticizer,the property of compound of the two kinds of superplasticizer liquid was systematically researched. The experimental results show that the composite superplasticizer has different effect on the property of superplasticizer and concrete,the water reducing ratio increases with the content of polyester-type superplasticizer increasing,the slump loss of concrete increases with the content of polyether-type superplasticizer increasing. In addition,the performance of composite superplasticizer was optimized by remixing adjunct to support reference for application and development of polycarboxylate superplasticizer.
